COMBINED SUPPLY, OVERFLOW, AND WASTE FITTINGS FOR SLOP-SINKS, BASINS, AND BATHS.

SPECIFICATION forming part oi' Letters Patent No. 405,933, dated .T une 25, 1889.

Application filed January Z0, 1888. Serial No. 261,432. (No model.)

T0 all whom it may concern.-

Beitknown thatl, FRANK. A. TVELLS, a citizen of the United States, residing at Allegheny, in the count-y of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Combined Supply, Overow, and Taste Fittings for Slop- Sinks, Basins, and Baths, which are fully set forth in the following' specification, reference being had to the accompanying drawings, forming part thereof.

Figure l is a vertical section throughaportion of a bath-tub containing my improved fitting. Fig. i. is a similar section through a hand-basin. Fig. 3 is a plan of the iitting,

the upper portion of the water-receptacle being broken away.

The purpose of this invention is to provide a cheap construction for a combined supply, overflow, and waste fitting of the same general character and action as I have-shown in my pending applications, Serial No. 254,272, filed November 4, 1887, and Serial No. 255,457, iiled November 18, 1887. The saving in cost as compared with the structures shown in these applications is eiected by making the overflowduct integral with the body of the Xture in a manner similar to the common form which is known as patent overliow, with this difference, however, that the overiiewduct receives the water at the lower end around the outlet from the basin and discharges it at the upper end, this being the reverse ot t-he arrangement in the patent overiiow.

In the drawings, A is the shell of the basin, sink, or tub.

A is the outer shell of the integral overflow-duct which terminates in the nipple a, the overflow-passage being the space A2 between said shells and leading to the over iiow discharge-orifice through the nipple a.

B is a cup which I prefer to make of metal, having a lateral eduction-orifice l), commencing interiorly in oval form, with its shorter diameter vertical, in order to save height in the tting, and thence merging into a circular orifice through the nipple B.

C is a thimble or tubular plug or hollow bolt exteriorly threaded over the middle portion of its length, and having at the upper end a flange C', which is perforated and forms the strainer.

D is a packing-washer.

E is the supply-pipe.

F is a T connected at the nipple a into the overflow-duct A2 from the basin and tub having its cross vertical.

G is a T with its cross vertical, which is connected by the short tube G and by the tube G2, respectively, with the nipple B and with the lower end of the cross of the T F.

H is a union nut, by means of which a IElail-piece I is joined to the lower end of the These part-s are assembled in the following manner: The hollow bolt or plug C is inserted down through the waste-aperture a of the basin and through the aperture a2, which in the ordinary patent overliow is the waste-discharge aperture of the overiiow-duct as well as of the basin. The packing-washer D is passed up onto the protruding lower portion F of the plug C, and the said plug is then screwed into the threaded aperture b in the upper end of the cup B, and after the other parts are in place, as will be described, the plugis screwed down until the flange C binds down close upon the bottom of the basin or tub and draws the cup B rmly up against the under surface of the washer D, which itself binds against the under surface of the shell of the overiiowduct, whereby a water-tight junction is et'n fected, and the plug C constitutes a sealed passage 'from the basin or tub across through the overflow-duct into the cup B, said thimble or plug terminating within the cup B at a point sufiiciently lower than the eductionorifice b to4 constitute of said cupatrap of sufficient depth to aiord protection against sewer-gas. Before this plug is thus screwed tight, however, the short tube G is screwed into the nipple B and the T G has its short branch screwed to the other end oi the tube G', its long branch being left vertical. The tube G2 is then connected to the upper end of the T G and the lower end of the elbow F, said junctions being provided, respectively, with the right and left threads. The plug C and the pipe-connection G2 will now be tightened up simultaneously and the overflow-connection IOO ' the tailpiece I.

will be complete. The outer vshell A of the integral overflow-duct is formed with an induction-oriiice through a nipple a', and the supply-pipe E is connected into the overflowduct at said nipple, which is located, preferably, a little above the bottom of the basin or tub. From` the upper end of the cross of the T F a suitable pipe F leads to a Ventilatingi'lue, and serves both to carry off foul gas and to prevent siphoning the water from the trap in the cup B.

As the cheapest, most convenient, and reliable method of connecting the iitting F and the supply-pipeE into the integral overflowduct, I provide holes m and n through the shell of the basin or tub A, and a hole f through the cross of the T F, in line with its short branch or stem, and I make the end ot said stem to fit about the end of the nipple and provided with a suitable interior shoulder to form the stop for the nipple, which is inserted within the said short branch of the T, packing or cement being employed, it' necessary, to render the junction between the T and the nipple water-tight, and like suitable means being employed at the holes 'm and f to make them tight. The bolt M is inserted through the hole 'm and through the short branch of the T F and out through the hole f, and a nut M', being applied and tightened on its outer end, clamps the T securely to the basin. In a similar manner, by means of the bolt N and nut N', the supply-pipe E may be secured in place.

I iind it convenient to utilize the strainer C as the flange by means of Whose resistance the thread on the lower part of the plug C is enabled to bind the cup B to the basin; but it is not necessarily soV utilized, and instead of ,that method a shoulder or iange C may beprovided on the plug C in position to bind upon the upper surface of the shell A oi' the overow-duct, thereby binding the cup B directly to said shell. p

The operation of this structure is substantially as in my other applications and patent above mentioned-namelyz When the stopper K is withdrawn from the upper end of the plug C, the water from the basin or bowl passes out through said plug into the trap formed by the cup B, and thence by way of the tube G into the waste-pipe J, connected to The supply having been admitted through E causes the overflow-duct A2 to be filled with pure water, and the height of such column, being of that of the water in the bowl and falling with that water, will have been forced up through the strainer-the flange Cand will have cleared said strainer of any impurities which otherwise might have lodged upon it, washing them .over through the plug C into the waste-pipe- When the supply is admitted, it will fill the tube, enter-' Y ing through the strainer C at the bottom, any excess passing out through the T F directly into the sewer.

It will'be seen that with the exception ofthe parts B and C all the other parts are regular littings, of small cost, and these two parts B and C are themselves` simple and of cheap construction, so that the entire apparatus can be cheaply applied to a basin constructed as cheaply as and very similarly to those having the integral overflow-duct described.

A modification in respect to the means of fastening the cup B to the lower side of the overliow-duct is shown in Fig. l. The bridge C2, which spans the waste-passage in the plug C below the seat of the stopper, as is usual, for the purpose of preventing the passage of small solid articles into the waste-pipe, has a central aperture, through which the bolt p is inserted, being stopped byits head above said bridge, the other end passing out through a hole p in the bottom of the cup B, and receiving on the protruding end, which is threaded for that purpose, a bindin gnutp2- For cheapness ,in construction I prefer in this case to make the strainer C by striking it up out of sheet metal in a separate piece from the plug C, the upper end of which in that case encircles the depressed portion, which forms the seat for the stopper K, and the plug C has th en the' flan ge c in position to bear and bind upon the upper surface of the lower wall A of the overiiowluct. Cement or a packing- 'gasket p3 prevents leakage around the bolt p, and by means of the nut p2 the cup B is bound iirmly up against the bottom of the overflow-duct, and at the same time the strainer C is kept in place.

This fitting is equally adapted and suitable without variation, except as to proportions, for any form of water-receptacle, whether. hand-basin, slop-sink, foot-bath, or plungebath, and by the term basin,7 as employed in the gen eral description of the structure and in my claim, I desire to be understood as including the water -receptacle of any such ixture.

I claim* In combination with the basin having an overflow-duct formed integrally with it and communicatingwith the outlet of the basin, a cup having an @duction-orifice communicating with the waste-pipe, and a tubular plug which opens at its upper end in the basin and at its lower end in the cup, and which pene-- trates the top of thecup and the bottom of the overflow-duct and forms a sealed passage through such duct from the basin into the cup, the supply-pipe connected into the integral overow-duct, the T F connected to the upper end of said duct, the tubular parts G and G2 connected, respectively, with the T F and the nipple B of the cup B, and the T G, connecting said tubes G and G2, and having its third mouth leading to the wastepipe, substantially as set forth.
